Three years ago, teenager Preeti Kumar was able to join a private school in Delhi thanks to the Right to Education (RTE) Act that made it mandatory for unaided private schools to reserve 25 per cent seats for disadvantaged children like her. But Preeti is an exception as a new report shows that only 29 per cent children like her benefitted from the law in the last academic year. In numbers that's just 6.1 lakh students though 21 lakh students could have gotten admission.
